Bruce Willis and the 'Red' Meat Rug

Promoting his new film "Red" on "The Late Show with David Letterman" Monday, Bruce Willis modeled what could the newest fashion craze for bald men -- a beef toupee!

"It's 100 percent ground beef sirloin," said the actor, whose inspiration came from Lady Gaga's meat dress at the MTV VMAs. "Top shelf, organic."
